EtherNet/IP to GE Ethernet Global Data Gateway

5201-DFNT-EGD

The EtherNet/IP protocol driver supports the Explicit Messaging implementation of the protocol. User-configurable as both a Client and a Server, the EtherNet/IP port is a very powerful data transfer tool.

The EGD modules offer one-to-one or one-to-many interconnect scenarios. Data is exchanged between devices and/or networks using a shared common database and an efficient but powerful wireless protocol. This common database provides the "backbone" communications for various field devices using different networks.

Funcionalidades e Beneficios

Applications

The DFNT-EGD modules are the ideal solution for the many applications where EtherNet/IP connectivity can be used to integrate GE Ethernet Global Data devices into a system. The EtherNet/IP protocol is one of the primary connectivity tools to the different Rockwell Automation platforms. The Explicit Messaging aspect of the protocol (only) has been implemented in the ProLinx units to provide the data transfer link between the ProLinx units and the Rockwell Automation hardware. (Implicit Messaging (I/O communications) is not supported). In combination with the GE Ethernet Global Data device support, the module provides a very powerful interface to the many EtherNet/IP devices which are in use in the industrial marketplace today. Applications for the module are found in most industries, especially Manufacturing, Oil and Gas, Electrical Power and Food Processing.

General Protocol Information

Messaging

PCCC on CIPExplicit Messaging supported

Miscellaneous

125 word read and write data lengthsFloating point data supported

EtherNet/IP Server Specifications

In Server mode, the module accepts commands from one or more clients to read/write data stored in the module's internal registers.

EtherNet/IP Server Specifications

Connections

Five independent TCP server sockets permit remote clients to interact with all data contained in the module.

In Client mode, the module controls the read/write data transfer between the gateway and other EtherNet/IP devices. Data transfer can be initiated and executed without any ladder programming being required in the Rockwell Automation hardware.

EtherNet/IP Client Specifications

General

One client

Command List

Support for 100 commands, each configurable for command, IP address, register to/from addressing and word/bit count.

Polling of command list

User configurable polling of commands, including disabled, continuous and on change of data (write only).

EGD Protocol Specification

Data is exchanged between devices and/or networks using a shared common database and an efficient but powerful wireless protocol. This common database provides the "backbone" communications for various field devices using different networks.

Protocol Specifications

GE Fanuc Automation and GE Drive Systems developed an Ethernet Global Data, or EGD, exchange for PLC and computer data in 1998. GE Ethernet Global Data (EGD) offers versatility where a mix of control devices requires cooperation with each other. This involves sharing of information across the applications regardless of device or network type, often at high speed, and with high reliability. Bandwidth utilization is optimized by using efficient communication methods. High reliability means fewer communication failures and having the ability to detect failures upon occurrence. Particular emphasis is delivered for applications requiring periodic or frequent updates and time synchronization of devices. The protocol supports Unicast, Broadcast and Multicast group messaging. Efficiency is based on the fact each device on the network can produce these types of messages and each device determines which of these messages to consume.

The module supports the following functions specified in the EGD protocol:
